IMPROVEMENT IN BUNGS.

Specification forming part of Letters Patent No. 217,225, dated July 8, 1879; application filed October 8, 1878.

'To all whom it may concern:

Be it known that we, JOHN R. JONES, of the city, county, and State of New York, and FRANK V. SANDFORD, of Chelsea, in the county of Suffolk and State of Massachusetts, have invented a new aud useful Improvement in Bungs, of which the following is a full, clear, and exact description, reference being had to the drawings accompanying and forming part of this specification.

Our invention is a hung, constructed as fully described hereinafter, to prevent displacement by the pressure of the fluid in a barrel, and to seal the opening between the bung and barrel at the inside of the latter.

in the drawings, forming part of this specification, Figure l is a sectional elevation, showing our improved bung applied to a barrel. Fig. 2 is a section, part of the device being removed; and Fig. 3 a detached view.

A is a tube or hollow cylinder of metal, divided internally by a transverse partition, to, on the top of which are two inclines, c c, with abrupt shoulders 00, and at the center of which is an opening, I). i

To the space within the flange c, forming the lower end of the cylinder A, is adapted a cylindrical block, B, having a flange, c, at the lower edge, and a central stem, f, which extends through the opening b and through a disk, O, adapted to the chamber at the upper end of the cylinder A, and having at the lower face two inclines, t' i, with abrupt shoulders 51 y.

A cross-pin, h, retains the disk 0 on the stem f, and recesses a in the top of the disk are adapted to receive the prongs of a key, X, by which the disk may be turned.

Around the body of the block B, between the flange e and the flange c of cylinder A, fits a rubber sleeve, D, which, in its normal condition, has a flat outer face, forming a continuation ofthe outer face of the cylinder A.

When the parts are in the position shown in Fig. 2,the bung maybe introduced into the hole in a barrel, after which, on turning the disk 0, the block B will be drawn within the. flange c, and the rubber ring will be compressed longitudinally an d distended laterally, thereby forming an annular rib, which not only effectually prevents the withdrawal of the bung, but also bears against the inner face of the tave, so as to close the space between the cylular may be the form of the stave at the mouth of the opening.

We claim- The combination of the hollow cylinder A, its central partition a, inclines e, the block B, its flange e and stem f, the disk 0, its inclines i, and rubber sleeve D, arranged between the flanges c and c, to be compressed against the inside of the stave, as set forth.
